PERFECTING PRINTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 369,792, dated September 13:, 1887.

Application filed November 2, 1883. Serial No. 110,624. (No model.)

To all whom it may concern.-

Be it known that I, RUDOLPH M. HUNTER, of the city of Philadelphia, county of Philadelphia, and State of Pennsylvania, have inventedan ImprovementinPerfectingPrinting- Machines, of which the following is a specification.

My invention has reference to printingpresses of the perfecting class; and it consists in certain improvements set `forth and claimed hereinafter.

The object of my invention is to provide a perfecting-press adapted to print circulars, newspapers, and book-sheets upon both sides before leaving the same, whereby less handling is required and more accurate printingis the result. As the paper is fed from a roll and automatically cut off into sheets and delivered printed upon both sides, the operation is of necessity rapid and inexpensive. In the ease of book-sheets, each type-form may contain different matter, corresponding to the different pages of the book or pamphlet, and as the said printed sheets are received and laid in their proper consecutive order the pamphlet can be at once bound. In case of printing circulars, they may be all of one kind or two or more kinds, and these can be regularly interposed between each other when delivered by the mechanism shown,or by si mple devices they may be kept entirely separate.

In the drawings, Figure lis a side elevation of my improved perfectingpress. Fig. 2 is a section on line y y of Fig. 3 and shows the transfer device. Eig. 3 is a cross-section on line @om of Fig. 1. Fig. 4 is a side elevation of a modified form of transfer-nippers. Fig. 5 shows a perspective view of one of the nipper-cranks, and Fig. 6 is a plan view of my improved perfecting-press; but in this View the mechanism for operating the fly, suction apparatus, 85o., are shown as arranged on the opposite side to that shown in Fig. l.

A is the frame of the machine.

B is the roll ofpaper, which is fed between the tension and feed rollers B', and from them it passes between the cutting-cylinders Baud after being severed into sheets they are intermittently fed by tapes b on rollers B3 to the tapes c c', passing, respectively, around the printing-cylinder C and the impression-cylinder H. The sheets, after being cut by cuttingcylinders B2, are not fed forward to the printing mechanism until the tapes b, which are continually moving, are pressed together,and this action is intermittent, being produced by the cam L and connecting mechanism, subsequently referred to. Y

The cylinder C is supported upon a shaft, C2, carried in suitable bearings in frame A, and is provided upon its circumference with pairs of type-form supports D D', in which each pair of forms E E is separated byalarge space, D3, and the forms of each pair by a small space, D, the object of which will be hereinafter set forth. The supports D D are made hollow, as at d, and these spaces communicate with the periphery of the cylinder C between the type E by small apertures d2, and with the atmosphere on the sideof the cylinder C by apertures cl, which latter open through asmooth surface,- D5. The apertures d2 in the type-supports D communicate with one end and those in support D with the other end. (See Fig. 2.) Working against the surface D5 and close to the impression-cylinders H H are the suction-boxes F F, which communicate with an exhaust blower or fan,G, by pipes f, and operate t-o exhaust the air out of said spaces d through apertures cl as they pass before boxes F F', and this in turn creates a suction on the surface of the cylinder C and carries the sheet along for a given distance for the purpose of insuring its delivery to or from the transfer-frame J, pivoted to the frame A between said cylinders H H. The blower or exhaust-fan G may be run by aspur-wheel, I, on shaft C2, meshing with the pinion g on the fan-shaft.

The impression-cylinders H have impression'surfaces h, separated by spaces and adapted to print from every alternate type-form, and are rotated by gearing h,which meshes with gearing C on the printingcylinder G.

The transfer-frame .I is secured to an axle, J', having a pinion, J, and journaled in the frame A,equidista'nt between the cylinders H H', as shown in Fig. 2. The transfer-frame may he made'of simply three fingers or three sets of ngers, according as to whether it is single or double, and these fingers may have their ends arranged to run in grooves or in spaces between the type-forms arranged upon the type-cylinder, and thus receive and de- IOO liver the sheet without injury to the typeforms. If desired, the spaces between these fingers may be filled in with shorter fingers, which, when the frame is down, do not quite touch the type-forms which pass beneath them. The frame is rotated so as to lift the sheet as it passes from 4under cylinder H over to cylinder H', and during such manipulation reversing it, and then returns quickly to its original position. It is rotated by a rack, K, reciprocated by a bar or rod, K', pivoted to a lever, KZ, which is actuated by a cam, L, which is rotated by a pinion, L', which meshes with spur-wheel I. A spring, k,keeps the lever KZ in contact with the cam. This cam L also rocks a lever, M, held against it by a spring, m, and this in turn, by a bar, IVI', actuates the loiwer feed-rollers, B3, by vibrating their frame B In place of using a single iiy or transfer frame,J,as shown in Fig. 2, a double clampingframe may be used, as Shown in Fig. 4, in which the two frames J are drawn together by a spring, J5, and cranks J3 are secured to the respective shafts j of the frames,and are provided with lugs J*,which alternately come in contact with the roller J6,held by the adjusting-screw J 7, which may be adj usted in the frame A and locked by nut JB.

The two frames J, shaft j, and cranks J3 all rotate simultaneously with the main axle or shaft J By this construction the two frames are separated until the sheet is received, and upon rising they close upon it, but open as they rest upon the cylinder O,next to the impression-cylinder H. Any other form of transfer device may be used, if desired.

The suction by box F' and form-support D' carries the sheet from the frame J and feeds it to the impression-cylinder I-I, which only printsfrom the forms on supports D', while the cylinder H only prints from the forms on supports D.

The printed sheet after passing between cylinders C and H' is carried off by tapes c c, which pass around rollers P P',and is received upon the fly-frame O, which deposits it upon the table Q. This iiy-fraine may be actuated by a rod, n', lever N', and cam-wheel N, having projections n.

rIhe type E may be inked by cylinder R, having distributing-rollersr, for transferring the ink from plate It' to said cylinder R.

'Ihe machine may be driven by a belt over the wheel H2 on the shaft of one of the impression-cylinders.

It is evident that two or more sets of impressioncylinders may be used and sheet-s simultaneously printed from two or more rolls of paper.

The operation is as follows: The sheet being cut off the roll of paper B by cutting-cylinders B2, and then fed at the proper interval between the cylinders C and H by the rollers B3 and tapes Z) c',which cause it to be fed between them with a surface speed substantially equal to that of the type and impression cylinders,

d,passing from under the box F, and theframe J is simultaneously rocked,carrying the sheet over, turning and placing it upon the cylinder Ojust as the type in support D' reach the end of frame J, and the aperture d' of this support is then in juxtaposition with the suc'- tion-box F', and-the suction created causes the forward end of the paper to cling to the cylinder C, which in its movement drags the paper sheet from the frame J and feedsit between the said cylinder and impression-cylinder H', where it is printed upon its other side. The sheet printed on both sides is then delivered by bands c o2 to the ily-frame O and is depositedupon the table Q.

I do not limit myself to the exact construction shown, as it may be modified in various ways without departing from my invention.

I do not claim, broadly, a large cylinder provided with two or more sets of type-forms, one or more pairs of impression cylinders adapted to print, respectively, from different type-forms of each set or pair, and mechanism located between saidimpression-cylinders to receive the sheet after being printed on one side, reverse it,and feed it to the second impressioncylinder to be printed upon the other side.
